| 1 | 基于平面线圈的基波脉振磁场构造方法研究显示文摘为了减小电磁式时栅位移传感器的原始误差,提出了一种基于平面线圈的基波脉振磁场构造方法。通过研究现有电磁式时栅磁场构造方法和平面线圈磁场分布特性,利用各次谐波畸变率THD(Total Harmonic Distortion)最小的优化算法,得到平面线圈最优化布置参数,并且在数值分析和有限元分析软件中得到了验证。根据这些参数设置,设计了基于多匝方形平面线圈的新型电磁式时栅位移传感器。在150 mm量程内,新型时栅原始误差为-32μm^23μm,较现有电磁式时栅位移传感器减小了42.3%。 | 黄奔 彭东林 武亮 张天恒 | 2015 | 传感技术学报2015，28，10： | 4 |
| 2 | Construction of Crack Perturbation Model and Forward Semi-analytical Model of Attached Eddy Current Sensor显示文摘Fatigue damage monitoring is critical metallic structure health monitoring of aircraft.The sensor should be high sensitive,easy to be integrated into structure and well adaptable for poor working conditions.Therefore,an attached eddy current sensor with flexible plane is put forward and its characteristics are analyzed.By extracting material′s conductivity as the crack features,forward semi-analytical model is established and parameter optimizations are carried out.Crack perturbation model of attached eddy current sensor is constructed,and perturbation voltages of sensing channels under three-dimension structural crack are obtained.To verify the sensor′s performance,monitoring experiment on crack extension is conducted under condition of 3 MHz frequency.The validation experimental results show that perturbation model of 2A12-T4 aluminum alloy agrees well with experiment results,and perturbation model errors of four sensing channels are within 25%.The attached eddy current sensor is capable of testing the crack nondestructively and measuring the crack extension quantitatively with the accuracy of 1mm. | 焦胜博 程礼 李晓微 李培源 高君宇 | 2015 | Transactions of Nanjing University of Aeronautics and Astronautics2015，32，3： | 0 |
